The nodejs package contains a symbolic link `/usr/bin/corepack` to a
file from the nodejs-npm package.
```shell
build/tmp/work/core2-64-poky-linux/nodejs/18.14.2-r0/packages-split/nodejs/usr/bin$ ls -l
total 31932
lrwxrwxrwx 1 jan jan 45 Feb 21 05:08 corepack -> ../lib/node_modules/corepack/dist/corepack.js
-rwxr-xr-x 2 jan jan 32694304 Feb 21 05:08 node
build/tmp/work/core2-64-poky-linux/nodejs/18.14.2-r0/packages-split/nodejs-npm/usr/lib/node_modules/corepack/dist$ ls -l
total 2428
-rwxr-xr-x 2 jan jan 614216 Feb 21 05:08 corepack.js
```
Due to the link, the build system detects a dependency from package
`nodejs` to package `nodejs-npm`.
Since the `nodejs-npm` package depends on plenty more packages the link
should be moved to the `nodejs-npm` package.
